Document Summary
Solids: particles close together, high density, incompressible, maintain shape. Gas: particles close together, yet free to move, definite volume, but take the shape of the container, particles far apart, low density, compressible, take volume and shape of container. Surface tension- the resistance of a liquid to an increase in its surface area. Capillary action- the spontaneous rising of a liquid in a narrow tube, which results from the cohesive forces within the liquid and the adhesive forces between the liquid and the walks of the container. Meniscus- the shape of the surface of a liquid when placed in a glass cylinder. Evaporation- the escape of molecules from the liquid state to the gas or vapor state. Sublimation- the process of going directly from the solid state to the vapor state without becoming a liquid. Condensation- the process by which molecules in the gaseous state return to the liquid state.
